An authoritative analysis of Executive Decree No. 22-384 and downstream polymer manufacturing requirements.
In accordance with Algeria's revised investment framework and Executive Decree No. 22-384, the Ministry of Industry has mandated structured integration targets for domestic automotive assembly plants. The industrial model has shifted permanently from Complete Knockdown (CKD) and Semi-Knockdown (SKD) "screwdriver" assembly to full-fledged domestic manufacturing. Automakers such as Stellantis (Fiat Oran Plant), Renault, and other emerging global ventures must meet localized sourcing targets of 30% within three years of inception, scaling progressively to 40% and 50%.
Automotive interior plastics make up over 15% of total vehicle weight. Main cabin components, including dashboards, door trim panels, pillars, headliners, and floor configurations, are manufactured using multi-layered co-extruded polymer sheets. Setting up a local **Vehicle Interior Sheet Extrusion Line** in Algeria is not merely a high-margin enterprise—it is a critical requirement for Tier-1 suppliers supplying components to local assembly lines.
Raw materials like Thermoplastic Olefins (TPO), Thermoplastic Elastomers (TPE), Polypropylene (PP), and Acrylonitrile Butadiene Styrene (ABS) are processed via specialized flat-die extrusion. By extruding these polymer matrices domestically, companies can circumvent high tariffs on importing pre-formed plastic parts, satisfy regional value-content rules, and reduce supply chain lead times from weeks to hours.
| Polymer Type | Vehicle Interior Application | Key Mechanical Performance Requirements | Gwell Extrusion Configuration |
|---|---|---|---|
| TPO / TPE | Soft-touch instrument panels, door panel skins, floor liners | Low VOC, UV aging resistance, ductile low-temp impact behaviour | Precision Calender + High-shear single/twin-screw extrusion |
| PP + Talc/Fibers | Interior pillar trims, load floors, seat backs | High structural rigidity, thermal dimensional stability | High-torque gas-assisted or direct compounding twin-screw |
| ABS / PMMA | Glove boxes, high-gloss console trims, door pillars | Scratch resistance, premium aesthetic finish, impact strength | Co-extrusion feedblock with multi-manifold T-die systems |
| PVB | Laminated safety glass, acoustic windscreens, HUD displays | Optical clarity, adhesion to glass, moisture resistance | Precision chill-roll casting under clean-room conditions |
Algeria holds a strategic advantage in North Africa's petrochemical sector, spearheaded by state enterprise Sonatrach and new development partnerships in Arzew and Skikda. The local availability of base polypropylene and polyethylene resins ensures a secure domestic feed stream for extrusion lines. Setting up a high-output Gwell sheet extrusion plant enables processors to utilize locally refined polymers, drastically lowering the raw material cost per metric ton compared to imported compound sheets.
We organize our advanced engineering assets into four specialized categories to serve distinct industrial manufacturing requirements.
Engineering parameters designed for maximum efficiency and quality output.
Fully integrated multi-component gravimetric dosing systems feeding into twin-screw co-rotating compounding systems. This ensures homogeneous distribution of talc, elastomeric impact modifiers, and UV masterbatches.
Equipped with internal deckling and advanced closed-loop thickness gauges (using beta-ray or ultrasonic scanning technology) communicating directly with the die's thermal expansion bolts to maintain thickness tolerance within ±1%.
Three-roll or four-roll calenders featuring independent heating/cooling zone control. Our systems are engineered to prevent internal stresses, ensuring structural integrity and precise surface graining.
Automobile interiors are subject to strict environmental regulations regarding volatile organic compounds (VOCs) and cabin fogging values (determined by DIN 75201 standards). Elevated levels of volatile compounds can cause fogging on car windows and degrade cabin air quality.
Gwell's high-performance extruders feature multi-stage high-vacuum venting systems. By operating vacuum degassing at pressures below 0.05 bar (with dedicated liquid-ring pumps), we strip residual monomers, solvents, and low-molecular-weight oligomers directly from the polymer melt prior to entering the extrusion die. This ensures the finished TPO, TPE, or ABS sheets meet the most stringent global VOC limits, making them fully compliant for integration into vehicle interiors destined for international markets.

Seamlessly navigating domestic industrial regulations and logistics to guarantee a smooth plant launch.
Investing in large-scale plastic sheet extrusion systems in Algeria requires close attention to import protocols and electrical configurations. Gwell machinery is fully engineered to meet local conditions, ensuring hassle-free installation and reliable operations.
The global automotive industry is increasingly shifting toward circular economy goals. Many vehicle manufacturers now mandate the use of post-consumer recycled (PCR) or post-industrial recycled (PIR) plastic compounds. Our sheet extrusion lines are optimized to process material blends containing up to 50% recycled polymers without sacrificing tensile strength or surface quality.
By using custom screw geometries, melt pumps for steady pressure control, and continuous backflush screen changers, Gwell machinery can process regrind flake mixtures without interrupting production. This enables manufacturers in Algeria to reduce material costs while aligning with international green standards.
Our machinery is manufactured to the highest quality and safety standards, certified by leading international testing organizations.

Find answers to common questions about setting up and running vehicle interior sheet extrusion lines in Algeria.
Our extrusion lines are optimized to process TPO, TPE, PP, ABS, PC, PMMA, and PVB resins, including high-filler formulas (such as talc-filled PP) and recycled blends (PCR/PIR), which are widely used by automotive parts manufacturers.
We integrate multi-stage vacuum degassing zones directly into the extruder barrel. Operating at pressures below 0.05 bar, this system extracts residual monomers and VOCs before extrusion, ensuring the final sheets comply with international standards like DIN 75201.
The typical time frame for design, manufacturing, assembly, and testing is 90 to 120 days. Shipping from China to ports in Algiers or Oran adds 30 to 45 days, depending on shipping schedules.
